In Bangladesh, middle school is not separated like other countries. Generally schools are from class 1 to class 10. It means lower primary (1-5), upper primary (6-10). From class 6-8 is thought as middle school. Grades 1,2,3,4 and 5 are said to be primary school while all the classes from 6 to 9 are considered high school (as middle school and high school are not considered separate) while 10-12 is called college.
